Method for service processing and user equipment

Abstract

A method for service processing and a user equipment are provided, and the method for service processing includes: starting a back-off timer, after receiving a rejection response message sent by a network side through a 3GPP access; and stopping the back-off timer and triggering a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires.

What is claimed is: 
     
       1. A method for service processing, applied to a user equipment registered with an access mobility management entity through a 3 GPP access network and a non-3 GPP access network, comprising:
 starting a back-off timer, after receiving a rejection response message sent by a network side through a 3GPP access; and 
 stopping the back-off timer and triggering a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires. 
 
     
     
       2. The method for service processing according to  claim 1 , wherein the rejection response message is a mobility management request rejection message, and the back-off timer is a mobility management back-off timer. 
     
     
       3. The method for service processing according to  claim 1 , wherein the rejection response message is a session management request rejection response message, and the back-off timer is a session management back-off timer. 
     
     
       4. The method for service processing according to  claim 3 , wherein, the stopping the back-off timer and triggering the service request process that is based on the 3GPP access when the non-access stratum notification message sent by the network side through the non-3GPP access is received before the back-off timer expires, comprises:
 stopping, when the non-access stratum notification message carrying a packet data unit (PDU) session identifier is received through the non-3GPP access network, the session management back-off timer matching the PDU session identifier; and 
 triggering the service request process. 
 
     
     
       5. The method for service processing according to  claim 4 , wherein a data network name (DNN) and/or single network slice selection assistance information (S-NSSAI) corresponding to the stopped session management back-off timer is the same as a DNN and/or S-NSSAI corresponding to the PDU session identifier. 
     
     
       6. A user equipment, registered with an access mobility management entity through a 3GPP access network and a non-3GPP access network, comprising a memory, a processor, and a program stored on the memory and executable by the processor, wherein the processor is configured to execute the program to:
 start a back-off timer after receiving a rejection response message sent by a network side through a 3GPP access; and 
 stop the back-off timer and trigger a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires. 
 
     
     
       7. The user equipment according to  claim 6 , wherein the rejection response message is a mobility management request rejection message, and the back-off timer is a mobility management back-off timer. 
     
     
       8. The user equipment according to  claim 6 , wherein the rejection response message is a session management request rejection response message, and the back-off timer is a session management back-off timer. 
     
     
       9. The user equipment according to  claim 8 , wherein the processor is configured to:
 stop, when the non-access stratum notification message carrying a packet data unit (PDU) session identifier is received through the non-3GPP access network, the session management back-off timer matching the PDU session identifier; and 
 trigger the service request process. 
 
     
     
       10. The user equipment according to  claim 9 , wherein a data network name (DNN) and/or single network slice selection assistance information (S-NSSAI) corresponding to the stopped session management back-off timer is the same as a DNN and/or S-NSSAI corresponding to the PDU session identifier. 
     
     
       11. A non-transitory computer readable storage medium, having a program stored thereon, wherein, when the program is executed by a processor, the following steps are implemented:
 starting a back-off timer, after receiving a rejection response message sent by a network side through a 3GPP access; and 
 stopping the back-off timer and triggering a service request process that is based on the 3GPP access, when a non-access stratum notification message sent by the network side through a non-3GPP access is received before the back-off timer expires. 
 
     
     
       12. The non-transitory computer readable storage medium according to  claim 11 , wherein the rejection response message is a mobility management request rejection message, and the back-off timer is a mobility management back-off timer. 
     
     
       13. The non-transitory computer readable storage medium according to  claim 11 , wherein the rejection response message is a session management request rejection response message, and the back-off timer is a session management back-off timer. 
     
     
       14. The non-transitory computer readable storage medium according to  claim 13 , wherein, the stopping the back-off timer and triggering the service request process that is based on the 3GPP access when the non-access stratum notification message sent by the network side through the non-3GPP access is received before the back-off timer expires, comprises:
 stopping, when the non-access stratum notification message carrying a packet data unit (PDU) session identifier is received through the non-3GPP access network, the session management back-off timer matching the PDU session identifier; and 
 triggering the service request process. 
 
     
     
       15. The non-transitory computer readable storage medium according to  claim 14 , wherein a data network name (DNN) and/or single network slice selection assistance information (S-NSSAI) corresponding to the stopped session management back-off timer is the same as a DNN and/or S-NSSAI corresponding to the PDU session identifier.
